I tried to build a toolchain with this, and it fails for me, during the host-gcc-final build step, with the following error message:

In file included from ../../../../libsanitizer/sanitizer_common/sanitizer_platform_limits_posix.cc:17:0:
../../../../libsanitizer/sanitizer_common/sanitizer_internal_defs.h:257:72: error: size of array 'assertion_failed__869' is negative

     typedef char IMPL_PASTE(assertion_failed_##_, line)[2*(int)(pred)-1]

I have built the following configuration:

BR2_sparc64=y
BR2_KERNEL_HEADERS_4_1=y
BR2_TOOLCHAIN_BUILDROOT_CXX=y
BR2_INIT_NONE=y
# BR2_PACKAGE_BUSYBOX is not set
# BR2_TARGET_ROOTFS_TAR is not set

Could you have a look?

Thanks!

Thomas
